On
the pictures on top right and left two "miniferns" that are difficult
to tell apart. Pictured on the right Proserpinaca pectinata originates
from i.e. Florida and because of that it is a little more resistant against the
high temperatures in our aquaria. Telling apart Hottonia inflata (at
the left on top) and Hottonia palustris (the native Water stock)
is even more difficult. The last one is very bound to the season and is often
offered at the beginning of April. Much longer than a year it mostly does not
keep well. ........ Growing conditions: much lighting,
temp.:< 25oC neutr. - soft and acid water Heteranthera zosterifolia.
At the bottom on the left and on the right are pictured two different appearances
of the plant. In aquaria lesser in size one often needs an file of plants that
are a little more refined while in bigger aquaria or more to the background een
leaf a little more robust would not be unbecoming. The way in which we shorten
Heteranthera zosterifolia is determinative for the utter form. If we remove
the tops and we leave the stalks where they are, the leafs will get lesser in
size always.
| When
on the other hand one pulls the plant out of the bottom and puts back only the
tops, they will become little by little always larger. Of course other causes
as the availability of nutritious matter and lighting play an important role. ..........Growing
conditions: a lot of light, poor bottom. Under in the mid: the Leiden plant
(Saururus cernuus); responsible for the worldwide fame of the Dutch
planted tanks. It grows very slow and because of that it was easy to form a so-called
Leiden street with it. Often the problem was that the leafs that stayed under
water for a long time were covered with algae and became filthy at last. That
is why at present they are less often used and are jostled by plants that are
easier to care like Lobelia. That is a pity, for such a Leiden street gave a special
and ultra-Dutch atmosphere. ..........Growing
conditions: passable lighting < 25oC Just like all plants with small lobs
minifern demand a good filter to discourage algae, which will bring the plants
to an end
